Every time i open duma os it loads up then quickly switches to this screen ????

Does this every single time, internet is fine but i cannot change anything in duma os, i have reset it by holding the reset for 30 seconds like 5 times now and it lets me do all the menu stuff until i close the web browser, upon trying to reopen it via the browser i get this every time.

What web browser are you using? Are you accessing via HTTPS or HTTP? Use it in an incognito window and ensure you're accessing via HTTP, also try both the IP 192.168.1.1 or 10.0.0.1 unless you're changed it and routerlogin.net

When did it start happening, after upgrading, changing a setting etc?

I am pretty sure i know what is doing it now, i just moved in to a new build house and there are strict rules on no holes in the walls for the first year so we have had to put up with a pre installed bt line, not great but it is only for a year, anyway it hooks up through the wall in a ethernet port to the front room which is where i plugged in my XR 500 as normal BUT it is a bt smart hub 3 which does not play nice with it, i tried shutting off the dhcs and the wireless on the bt hub to try and remedy it but that just switches them all back on anyway as soon as i hook up the xr 500, i was thinking about plugging the xr500 straight into the line instead of the bt hub to cut it out all together but i have no idea what i have to change on the xr500 to make it go smoothly.

So basically i reckon this problem is purely because the bt smart hub 3 does not like another router being placed in it like earlier models, any ideas would be great :).

That shouldn't affect your ability to access its interface though - when you were trying to access the XR were you connected to the XR directly via WiFi or ethernet or were you connected to the BT hub still? If the latter then it makes sense and you wouldn't be able to. You could give the XR a static/reserved IP on the BT hub which could help and then put it in the DMZ.
